Discovering an unpredicted sentry(s) while moving along the created path can be easily accommodated.
At each free-space cell, the visibility risk cost to each sentry observing that cell is calculated.
The calculated visibility cost of that sentry at each affected cell is added to the previously stored cost.
The robot is exposed to the sentry at a far distance where it is more covert than the other shortcuts to the goal.
The new path is hidden from the known sentry but is still cautious from the unknown ones, as compared to the short path.
The approach has shown its capability of adapting with different levels of knowledge about both the operating environment and the sentries' locations.
This ability is important as it allows the robot to immediately maintain its covertness once it gets in the view field of an unpredicted sentry.
The estimated value at any location represents the risk level of being exposed to one or more sentries.
The approach depends on estimating a cost value at each free-space location that presents the risk of being seen by any sentry.
The shortest path on the other hand is exposed to all sentries.
It's in the middle of their line, like a sentry standing guard.
Only the cells that are in the view field of the discovered sentry are updated in the visibility map.
Different applications would have different visibility risk factors that should be taken into account, other than simply being/not being observed by a sentry.
The final visibility cost at a cell would be the sum of all visibility costs calculated for each of its observing sentries.
A short (dashed-line) path is observed by one of the sentries.
